Question

嗨，大家好我在学校的一个项目工作，我遇到了一个问题，我能够将UDP数据包发送到不同的地址，但我收不到发送到我的iPhone的UDP数据包，收到UDP数据包后，我想要数据出现在标签上，我做错了什么但我不知道是什么.....我的代码：

- (BOOL)onUdpSocket:(AsyncUdpSocket *)sock didReceiveData:(NSData *)data withTag:(long)tag fromHost:(NSString *)host port:(UInt16)port
{
    NSLog(@"Incoming data");

    [sock receiveWithTimeout:1 tag:0];
    NSString *receiveddata = [[NSString alloc] initWithData:data encoding:NSASCIIStringEncoding];
  //  NSString *receiveddata = data ;
    self.testudp.text = receiveddata;
    return YES;
}

Answer 1

这就是我所做的改变：

AsyncUdpSocket *udpsocket;
udpsocket = [[AsyncUdpSocket alloc] initWithDelegate:self];
[udpsocket enableBroadcast:YES error:nil];
[udpsocket bindToPort:1234 error:nil];
[udpsocket receiveWithTimeout:-1 tag:0];

- (BOOL)onUdpSocket:(AsyncUdpSocket *)sock didReceiveData:(NSData *)data withTag:(long)tag fromHost:(NSString *)host port:(UInt16)port{
    NSLog(@"received data");
    NSString *receiveddata = [[NSString alloc] initWithData:data encoding:NSASCIIStringEncoding];
    _testudp.text = receiveddata;

无法在Iphone w / AsyncUdpSocket上接收UDP数据包
